  • the typical solution is to store the combiner inside the unit and preferably close the gap with a cover.
  • the AR-HUD systems are more complex systems and the information is typically projected into a larger area of the windshield. These systems generate a virtual image projection and allow an interaction with the real scenario in front of the driver.
  • the W-HUD systems are quite similar to the C-HUD, but in this case the projection is made on a smaller area of the windshield instead of using a combiner.
  • the movement of the combiner can be made with different trajectories: rotation of the combiner (documents JP 2012-254708 and EP 2541303) and translation/rotation of the combiner.
  • the translation/rotation can be defined by almost vertical trajectory (documents WO 2013168396, WO 2013059662, US 20140320382 and US 20120188650), horizontal (documents US 20130194518, US008077396B2, US007978414B2 and US007869129B2) and also diagonal (document WO20131572389 or document DE102012209111).

  • the kinematic system of the present disclosure not only protects the combiner but also ensures the total coverage of C-HUD unit.
  • the total coverage of the C-HUD unit avoids the dust entrance and makes the unit more robust to misuse cases.

  • the combiner drive mechanism is based on a four bar linkage.
  • This HUD system is composed by: a combiner support for holding the combiner, a bar (lever) that can rotate about a shaft and is positioned at one end of the bar and the other extremity is connected to the support combiner.
  • the first bar is the motor bar and the second bar is the moved bar, only responsible to guide the combiner support and combiner along the movement between park and store position, through a translating/rotating movement.
  • Document EP 2 541 303 relates to a HUD system that contains a combiner, a cover and a gear mechanism responsible for simultaneously rotate the cover and combiner.
  • the cover stays parked inside the central box and when the combiner is in park position the cover will stay above the combiner.
  • This mechanism makes possible to expose the combiner when it is to display information in the combiner and the cover is hidden inside the box.
  • a cover will protect by means of a cover.
  • the angular trajectory of the cover and combiner is approximately 90 ⁇ .
  • the gear mechanism consists of a planetary gear comprising a sun gear coupled to the combiner, and a ring gear segment coupled to the plant gear.
  • the present invention includes a kinematic mechanism for combiner and/or other displays wherein the mechanism moves simultaneously the combiner unit and the protective cover using just one motor (preferably DC motor).
  • the combiner movement between retracted position and display position (extended position) can be completed between 3 and 6 seconds and vice-versa.
  • the combiner When the combiner is in display position, it allows an angular adjustment.
  • the angular adjustment of the combiner allows setting the position of the information into the combiner.
  • This angular adjustment is related with ergonomic standards in order to adapt the information position with different driver ' s height.
  • This adjustment can be ensured by means of a motor resolution.
  • the motor is permanently connected to combiner gear axis and consequently the angular adjustment is made by the number of revolution of the motor.
  • the driver may then have a manual switch to set the ideal projected information. This has the advantage that the same movement of rotation into the display position of the combiner is used for adjusting its position, making the mechanism and the control electronics both simpler to build and operate.
  • the synchronized movement of combiner and cover is preferably ensured by a system that possesses a pin on the cover gear and a slot on the Geneva gear. When the pin travels along the Geneva gear slot, this makes the cover gear rotate together with the combiner gear and support.
  • This part-synchronization movement could also be done with other kind of synchronization mechanisms, such as special gear trains (e.g partially toothed gear for distinguishing between two movements), bars linked to a camwheel (for obtaining two movements between a circular path and a non-circular path), ratchet pawl system (for obtaining two movements between a ratcheted and a non-ratcheted movement sections), clutch (for obtaining two movements between an engaged and a non- engaged movement sections) or with an additional actuator (e.g. solenoid or linear actuator) for engaging a second movement.

  • This movement can also be done with resource to an embodiment using camwheels linked to the cover and connected to several bars that are responsible for combiner rotation. The paths existent in camwheels will ensure the correct synchronization.
  • the ratchet pawl with simple features can also allow the desired behavior of the mechanism.
  • the pawl When the pawl is coupled to a tooth that belongs to the gear, the pawl will rotate the combiner.
  • a further embodiment may use an additional actuator which can be applied to the system in order to ensure the different movements of the head-up display kinematic system.
  • the C-HUD systems are typically composed by highly complex kinematic mechanisms responsible for combiner motion between the retracted position and the display/extended position.
  • the mechanisms should ensure the repeatable positional accuracy because an incorrect position of the combiner causes image distortions in the combiner.
  • the optic elements are very sensitive to small displacements which lead to imperfect image projection in the combiner and the different parts of the kinematics should be manufactured taking into account close tolerances. However, the need for so demanding tolerances has the immediate effect of increasing the costs associated with the manufacturing.
  • the design of these systems usually requires a very careful design to ensure excellent quality parameters. Most of the time, the technical specifications are related with kinematic noise levels, exposure to high temperatures, humidity and undesirable vibrations.
  • the package of the C-HUD system usually is dependent of several parameters of dashboard components position like instrumentation cluster and air conditioning pipes. Moreover, when a C-HUD system is assembled in a dashboard, it should be expectable the existence of a protective cover in order to avoid any damage to the combiner. Another important issue is the possibility to adjust the combiner angular position when it is in display/extended position. With this, the C-HUD system can be capable of adapting to different driver heights.
